And another angel came out of the temple, calling with a loud voice to Him who was sitting upon the cloud, “Put in Your sickle and reap [at once], for the hour to reap [in judgment] has arrived, because the earth’s harvest is fully ripened.”

The harvest

For thus says the Lord of hosts, the God of Israel:

“The Daughter of Babylon is like a threshing floor
At the time it is being trampled and prepared;
Yet in a little while the time of harvest will come for her.”

Also, O Judah, there is a harvest [of divine judgment] appointed for you,
When I restore the fortunes of My people [who have been slaves to the misery of sin].

and the enemy who sowed them is the devil, and the harvest is the end of the age; and the reapers are angels.

For the press

“I have trodden the wine trough alone,
And of the peoples there was no one with Me.
I also trod them in My anger
And trampled them in My wrath;
And their lifeblood is sprinkled on My garments,
And I stained all My clothes.

“The Lord has rejected all the strong men
In my midst;
He has proclaimed an established time against me
To crush my young men.
The Lord has trampled down as in a wine press
The Virgin Daughter of Judah.

Then another angel came out of the temple (sanctuary) in heaven, and he also had a sharp sickle.

For their

But the men of Sodom were extremely wicked and sinful against the Lord [unashamed in their open sin before Him].

Then in the fourth generation your descendants shall return here [to Canaan, the land of promise], for the wickedness and guilt of the Amorites is not yet complete (finished).”

And the Lord said, “The outcry [of the sin] of Sodom and Gomorrah is indeed great, and their sin is exceedingly grave.

And the vats shall overflow with new wine and oil.
